Description

Technical Field

[0001] The utility model belongs to the technical field of metal parts processing, in particular to a parts bending and bonding device. Background Art

[0002] The welding between large and long metal parts first requires the contact surfaces of the two to be fitted. The traditional method is to manually use a jack to bend the non-contacting parts one by one. Due to the limitations of the parts' own materials, the bending process needs to be performed in multiple rounds until all points are in contact with another part. At the same time, due to the lack of continuous pressure on the part surface after bending, the part shape will rebound, affecting subsequent welding work. Utility Model Content

In view of the shortcomings of the prior art, a parts bending and bonding device is provided.

[0006] Furthermore, the hydraulic cylinder includes a first hydraulic cylinder and three second hydraulic cylinders.

[0007] Furthermore, the front end of the shaping column fixedly connected to the first hydraulic cylinder is fixedly connected to a limiting column, the shaping column and the limiting column are coaxial structures, the diameter of the shaping column is larger than the limiting column, the bottom of the rectangular block is fixedly connected to the first hydraulic cylinder mounting seat, the side opening of the rectangular block is coaxial with the shaping column, and the inner diameter is the same as the diameter of the shaping column.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] 2) No need to bend parts multiple times, reducing time costs;

[0011] 3) The auxiliary workbench and auxiliary base improve the compatibility of the device;

[0012] 4) The stable pressure from the hydraulic cylinder prevents the shape of the parts from rebounding after bending, which is conducive to the normal development of subsequent welding work. BRIEF DESCRIPTION OF THE DRAWINGS

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the present invention, unless otherwise clearly specified and limited, the terms such as "connection" shall be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, or it may be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The side plate 3 is provided with the positioning hole 1, and the workbench 5 and the auxiliary workbench 8 are both provided with the fixing hole 4. The positioning column fixes the workbench 5 to the side plate 3 through the positioning hole 1.

[0021] The three first limiters 2 and one second limiter 7 are all fitted with the side panel 3, the three first limiters 2 are fixedly connected to the workbench 5 and the base 6, the left side of the base of the second limiter 7 is fixedly connected to the workbench 5 and the base 6, and the right side is fixedly connected to the auxiliary workbench 8 and the auxiliary base 9.

[0022] The bent plate 12 is in contact with the surface of the side plate 3. To facilitate subsequent welding, the side plate 3 is provided with three horizontal openings. The bent plate 12 is provided with openings with the same inner diameter at corresponding positions and is pre-fixed with two fixing bolts.

[0023] The auxiliary workbench 8 and the auxiliary base 9 have the same length and width, and the superimposed height of the two is the same as the superimposed height of the workbench 5 and the base 6. The auxiliary workbench 8 and the auxiliary base 9 have various sizes. Whether to install the auxiliary workbench 8 and the auxiliary base 9 and the installation specifications are determined based on the horizontal size of the parts to be processed.

[0024] The working surface of the hydraulic cylinder faces the bending plate 12, and the shaping column 13 is fixedly installed outside the piston rod to bend the bending plate 12. The number of the hydraulic cylinders depends on the number of points on the part that need to be bent. The hydraulic cylinder described in this embodiment includes a first hydraulic cylinder 10 and three second hydraulic cylinders 11. The front end of the shaping column 13 fixedly connected to the first hydraulic cylinder 10 is fixedly connected to a limiting column 15. The shaping column 13 and the limiting column 15 are coaxial structures. The diameter of the shaping column 13 is larger than that of the limiting column 15. The diameter of the limiting column 15 is the same as the inner diameter of the three horizontal openings of the bent plate 12.

The side opening of the rectangular block 14 is coaxial with the shaping column 13, and the inner diameter is the same as the diameter of the shaping column 13. When working, the piston rod of the first hydraulic cylinder 10 extends forward, driving the shaping column 13 and the limiting column 15 to pass forward through the lateral opening of the rectangular block 14. The limiting column 15 is inserted forward into the horizontal opening reserved for the bent plate 12 to fix it. The shaping column 13 fits the surface of the bent plate 12 to bend the bent plate 12.
